    During the AC busy season, I was pleasantly surprised to be able to get an AC maintenance appointment the following day. Eddie, the technician arrived as scheduled and made sure my AC was functioning as it should. He communicated well and answered any questions I had about the AC. Ultimate Air employees are very professional and I found the charges to be reasonable. I feel fortunate to have Ultimate Air to take care of my AC and heater.

  • Ryan Z.

    Ultimate Air Conditioning is by far the best a/c heating company I have found in the valley. Very professional, trustworthy, clean and fairly priced. They installed a ductless split AC unit. Was quoted 3-4 hours ended up wrapping it up in under 2 hours with cleanup. I would highly recommend this company to all my friends and family.

  • Jessyca

    I am a busy Los Angeles/San Fernando Valley real estate agent who really needs to be able to trust & rely upon the service people I recommend. Ultimate Air Conditioning is A+++! I can refer Erez & his professional team of technicians to my clients, family, neighbors & colleagues with the utmost confidence. I know they will be honest & fair. Communication is awesome; someone always answers the phone or calls back within minutes. Service is unbeatable; knowledgeable & friendly. Ability is vast; from service calls to new system installations, they are precise & everything is done correctly. I give Ultimate A/C ten stars!!

  • Kathleen W.

    I really appreciate the timely fashion they came out to check my office AC unit. Nothing ended up being wrong with it but that burned smell (neighbor's business burned incense) freaked me out. They were fast, professional and thorough. Just what I wanted.

    As the name of this company implies,Ultimate Air Conditioning, has provided the ULTIMATE in customer service hence efficacy and professionalism. I had reached out to a couple companies, in the attempt to resolve an ongoing technical issue I had encountered with my air-conditioning unit. Needless to say, not only these attempts failed, but it had gotten worst; I was told I may have to replace the unit. Luckily, a good friend had recommended Ultinate Air. The costumer service was impeccable, the level of professionalism hence efficacy goes beyond words. I have been astonished to see how quickly they were able to resolve the problem, in which other companies had failed to do. I Highly Recommend this company.

  • Tom N.

    Erez, Eddie, and the team are awesome - professionals with expertise and not trying to fleece anybody. Accurate diagnoses of problems as well as the best solutions to fix them. The best.

  • Matthew R.

    Erez was straightforward and informative about my options to move or replace my HVAC condenser to bring it up to code (too close to electrical panel). Offered me a very competitive quote to do either job. Ended up just moving it; he and Michael showed up on time and completed the job quickly and correctly. Will definitely use them again.

  • Gordon P.

    professional and knowledgeable. I had two other companies come by. One is still trying to figure it out. The other said that we needed a new forced air and condenser. Ultimate fixed it for less that $400.00. I will use again and refer.

  • Karina N.

    They are incredible! Knowledgeable, on time and all-around wonderful people!

  • Helena

    Technician was knowledgeable, explained how to approach the problem methodically & did not try to oversell. Good experience.
